its funny how the bad guys always keep the stunned good guys alive and lock them somewhere even though they're going to kill them all later.
I lost count of how many times it happened. last time it was with Todd stunning everyone on the ship and locking them in a room even though he was gonig to crash the ship and kill them later. as a wraith with diminising food supply he wouldn't thrown away so much food. he would have fed on them before leaving.
now the same story with michael locking everyone up even though he was going to blow up the city anyway. why take the trouble of dragging them all to a room and leave them alive?
and leave only 1 guard at the door.
and since he was just standing there doing nothing the whole episode except ordering his henchman to arm the self destruct, why not take the baby and leave and tell his henchmen to finish the work themselves?
